The 5.13 percent inflation is the highest in two months, and a higher inflation than this level was last seen in July at 5.27 percent.

Data released last week showed retail inflation rose to 3.77 percent in September from 3.69 percent in the previous month. The RBI mainly takes into account retail inflation data while formulating monetary policy.

In its fourth monetary policy review for the fiscal last week, the Reserve Bank maintained status quo on the benchmark interest rate but warned that volatile and rising oil prices, and tightening of global financial conditions pose substantial risks to the growth and inflation.

For October-March, the RBI pegged CPI-based retail inflation to be between 3.9-4.5 percent.
